Popis: The NSLS-II storage ring completed commissioning in 2014 and all project-beamline IDs have also been commissioned. As of February 2015, six beamlines are about to finish commissioning. By the end of 2015, the ring is expected to store 300 mA with top-up injection capability and 500 mA with a second superconducting RF cavity installed in the following year. The design principle of the NSLS-II ring is to employ low-field BMs and simultaneously install high-field wigglers in non-dispersive straights to reduce the horizontal emittance. The more wigglers are installed, the smaller the horizontal electron beam emittance becomes. At this stage, six 3.4-m-long wigglers with 1.8 T effective field and 100 mm period length have been installed in three straight sections, which could reduce emittance in a bare lattice from 2.1 nm.rad to approximately 1.0 nm. rad. Two 2.0-m-long EPU49s are installed for the coherent soft X-ray (CSX) beamline in a short straight (SS) section also known as the low-βx straight section. Th...
